This invention pertains to a Application February 20,

1 Claim.

hollow brick wall construction and more particularly to a novel means for bonding the oppositely disposed brick walls of a hollow wall construction together and to a method of constructing said bond.

A primary object of the invention is to provide a novel bond which includes T-shaped bricks used in conjunction with brick of common shape to provide a bond or inner walls whereby tie between said outer and the bricksof said tie are susceptible of being layed by the operator employing motions of the hand in a horizontal direction solely.

An important object of the invention is to provid a novel bonding or tying means for hollow to provide a hollow or bond course of to provide broken wall construction, the header which is entirely concealed; horizontal mortar joints, so

arranged that moisture is prevented from traveling by capillary attraction through the wall; to provide a light weight wall at a reduced cost requiring a comparatively less heavy foundation; to

provide a wall the about window casings; to

bricks of which are easy to fit provide a wall which will preclude the admission of moisture or cold air while having a continuous vertical air space to insulate against the transference through the wall of frost and dampness; to provide a hollow brick wall construction in which vent, soil, water, electrical conduit and other piping may be conveniently and greater bearing surface between the overall purpose of means for readily installed; to provide a the bonding providing a greater degree of strength and rigidity than heretofore commensurate with the labor and material expended, said wall construction to be simple,

strong, durable and inexpensive.

The invention resides wholly in the combined wall construction itself, no claim being made to any of its constituent elements as disassociated therefrom.

With the foregoing and other objects in view the invention will be more fully described hereinafter and more particularly pointed out in the claims appended hereto.

wall construction embodying the present invention.

Figure 2 is a perspective View of a wall end brick which may be employed.

Figure 3 is a perspective view of a T-shaped brick employed in conjunction with common bricks for providing a bond or wall tie.

Figure 4 is a perspective view of a hollow brick wall constructed in accordance with the present invention and showing closure means for capstones which may be employed.

As heretofore practiced in the art C-shaped bricks as well as bricks having their corners clipped off and also round-end tie bricks have been employed in the tie or bonding course of hollow brick wall constructions. The C-shaped bricks necessitate placing the tie bricks between the arms of the C from above after the C-shaped bricks have been layed with the consequent loss of labor, material and loss of strength in the tie or bond. Clipped bricks have required much extra labor for hand clipping and loss of time as well as extra mortar material in laying. Tie bricks having round ends which member in circular recesses have the disadvantage that said round ends cannot be readily buttered with mortar. That is to say the mortar cannot be applied to the bricks from the trowel with a single motion and it is an object of the present invention to obviate the undesirable features of the prior art.

Referring now to the drawing for a more particular description, 10 indicates generally a hollow brick wall formed of an inner wall HI and outer wall l2 which are oppositely disposed and spaced from each other to provide a vertically disposed space A therebetween, said inner and outer walls being tied together by a means later described.

The walls H and i2 include a plurality of courses of brick l3 each being of T-shaped contour in plan and disposed with the heads of the Ts in horizontal alignment, providing rectangular recesses i4 between the stems of adjoining T-shaped bricks. Said T-shaped bricks may be used solely in the bonding courses of the wall or the entire wall may be made therefrom and the L-shaped brick l5 may be employed for building wall corners or wallends.

Preferably the bonding courses are formed at regular intervals in said outer and inner walls whereby the rectangular recesses M are provided upon the inner opposed faces of said walls with the recess M of one wall being oppositely disposed with respect to the recess l 4 of the opposite Wall.

Common bricks l6 are used for the bonding or tie bricks, said common brick being rectangular in plan and secured between said outer and inner walls, the ends of said rectangular common bricks engaging the rectangular recesses formed by said adjoining T-shaped bricks of each bonding course.

The top of the wall may be closed by the employment of common bricks or the c'apstones l7 employed for said purpose.

The mortar joints l8 are conventional as to the material. In laying bricks in the bonding courses it will be noted that the common tie brick I6 is buttered and laid into position in abutting relationship with respect to a T-shaped brick of each wall and before the next adjoining T-shaped brick is placed into said wall whereby the tie bricks are laid with horizontal motions solely and in a manner requiring fewer motions and less time and labor than has heretofore been practiced in the art. A further advantage in placing the tie brick as above described is that a stronger bond is provided since after a tie brick is buttered the mortar is compressed during sliding of the tie brick into place.

What I claim is:

A hollow wall construction comprising at least two spaced apart wall members, a plurality of superposed T-shaped bricks in each of said wall members, said T-shaped bricks in each of said wall members having their arms extending along the longitudinal axis of the wall and their legs extending'inwardly and transversely of said axis to cooperate with one another to form a plurality of oppositely aligned semi-rectangular shaped recesses, and rectangular tie bricks secured in said recesses to bond the said Wall members.
